Back at the time when Vinicius Junior joined Real Madrid squad, he wasn't any better than Kylian Mbappe right now and I remember Benzema saying about him to his mates, that he is playing against us. Everything takes time and we all know about the quality and performance of Mbappe.
Mbappe is a very talented player. And he could score plenty of goals in the future if he settles into Madrid's squad. We have seen Vini perform very poorly a few seasons ago. Even he missed many easy opportunities. But Ancelotti gave Vini enough opportunities. And at the moment one of the most important scorers in the Madrid squad is Vini. So Mbappe is yet to perform as well as expected with Madrid. But given enough time and opportunities, Mbappe should be able to adapt to this team. However, in the last match we saw a much better performance from Mbappe. Mbappe has to maintain this consistency.
In as much as it's expected of Kylian Mbappe to be up and running in his scoring of goals at Real Madrid and starts performing as expected, but it still very early to expect that such performance from him, despite his an incredible player that wouldn't find it very difficult to adapt and blend into any team which he finds himself, Mbappe has just had few weeks play time at Madrid, to me I won't expect much now from until after his first season, but he does performance well, then good.
